Set the gap on 0.035" or .9mm

For what engine,or google ngk ,champion whatever

gap is defined by motor your putting the plug in

they are pre gapped but its suggested to check gap as it could be altered during shipping.

Briggs & Stratton Part Number 799876 replaces Champion plug RJ2YLE. For use in Quantum Series 625, 675, and 725 engines built after Date Code 110701xx. The gap for this spark plug should be set to .020". This spark plug should not be used with Quantum Series 625, 675, and 725 engines built before Date Code 110701xx, or any other L-head engine family.

I'm guessing you have a standard Champion J19LM plug, which has a gap of .030. They come pre-gapped from the mfg. and usually no need to adjust them. Most of the plugs on these engines have a .030 gap. There are very few exceptions that use a .020 gap (such as the RC12YC). Anyway, here's a link to a chart I like to use for reference: (there's a drop down menu at the top to change engines, but the standard Briggs engine is the one here).
